What is Mailcow Aliases?

Mailcow Aliases is a Safari extension that enables users to generate disposable email forwarding addresses directly from their own Mailcow server. It prioritizes data privacy by bypassing third-party services and storing API keys locally in the system Keychain. The app provides a native interface for managing aliases on both macOS and iOS.
